If you’re like most iPhone SE owners, you probably just want to be able to use your phone the way it was meant to be used: without having to worry about a pesky sim card. Here’s how to put a sim card in an iPhone SE:

  1. Open the phone’s battery cover and remove the battery.
  2. Insert the sim card into the phone’s microSD slot. Make sure that it is fully inserted into the slot and that there are no gaps between it and the phone’s casing.
  3. Replace the battery and close the battery cover. ..
